IMPROVEMENT IN DMPING-WAGONS.

TQ ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY SHIREY,Vot` the c'ity of Fond du Lac, in the'county'of Fond du Lac, and in the State of' Wisconsin, have invented certain new and useful Improvements in Dumps for Vehicles; and I do hereby declare that'the'following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of refrence marked thereon, in which- Figure 1 is a side elevation.

Figure 2, an end view.

Figure 3, a section in perspective.

Figure 4, a section with the side ofthe bed of the vehicle removed.

The nature of my invention consists in the construction of a dumpcr-bed or body for wagons, as hereinafter described.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation. v

In the construction of my invention I make the bed or body ot' the wagon of any convenient form, as seen in iig. 1. A, the bed 'or body of the wagon; b b Zz Z1, the bottom boards, with loops,A c c c e, attached to each board, lfor the purpose of drawing them out; dd (Z rl are revolving supports, on which the bottom boards rest. These supports are composed ot' two parallel bars joined together with cross-bars CZ', the lower bar being the longer ofthe two, and is fixed in supports e e, which supports are rmly attached to the lower bed-rail in any suitable way. To the outer end of each of` the revolving supports d, I attach a cam,f, which is connected to the sliding bar g, thus connecting each of the revolving supports to this slidingbar. At the rear end of bar g is attached a lever, 7L, with its fulcrum, c, (which is a headed bolt attached to th'o front end of the bed-rail, and said lever extends up nearly the height ofthe bed or body of the wagon; and when the braces are turned into position to support the bottom, this lever is held in position by a revolvingbrace, z', attached to the side of p the bed, (as seenl in g. 1,)`and which `holds the gate B shut. Cross-barsjjare placed across the bottom,

attached to the under side ofthe bottom rails of the bed, t-,o prevent the bed from spreading` apart.

In the operation of my invention, when I wish td load the vehicle, the boards of the bottom having been placed in proper position, the lever z4 having been pushed backward, thesupports d are turned down on their sides, so as to easily adjust the boards b. When thus adjusted, the lever 7L is drawn up, pushing back the bar g, carrying the revolving supports d up to a vertical position, and pressing them against a cleat onthe front end, and the gate B at the rear end. The upper bars `of' supports d being pressed tightly up against the boards b, hold them in place, at the same time supporting them so that the cross-bars that are commonly framed in the bed are dispensed with. I Thus prepared, the bed may be filled or loaded, and the vehicle removed to any required pla-ce with its load'in perfect safety. When it is required to d'ump the load, it is only necessaryto detach the lever L from 4the brace c', and by'its own weight the load presses down the supports d, and relieves the boards oi' the pressure oi' thc supports. The boards 6 are then caught bythe loops c, and are readily drawn out, thus directly dumping the load. It requires comparatively but a small amount of force to draw out one of the boards 11 at a time; and after the 'first board has been drawn, cach succeeding board is drawn out with less resistance, as parti. of the load fall through the first opening, greatly relieving the pressure on each succeeding board, and thus the operation is completed` `Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The revolving supporters cZoZCZ d, camsf, b'ar g, lever it, fulcrum 7c, and brace z', constructed substantially as described and operating as set forth.

2. The bottom boards b loops c c, in combination with a body or wagon-bed, when constructed and operating substantially in the manner and for the purposes set forth.

In testimony that I claim the above-described certain new and useful improvements in dumps for vehicles, v I have hereunto signed my name, this twentieth day of August, 1867.
